Re: How to deal with "Out of memory detected" during reasoning?

Hi Wentao,

You need to increase the memory available to Protege.  There are some instructions here:  http://protegewiki.stanford.edu/wiki/Setting_Heap_Size

I don't believe the reasoners in Protege 3.5 will ever be updated.  Protege 4 is underpinned by a different API to Protege 3, which more reasoners (and newer reasoners) provide implementations for.  Hence, if you want more robust reasoning support and more up to date reasoners you probably need to use Protege 4 (4.2). 

Cheers,

Matthew

And now, the Jess rule engine which can support SWRL well and used widely, right? Does it mean the pellet will be replaced by Jess or other rule engine? at least, the pellet 1.5, I think, is old for protege 3.4 or later.
